Abstract: 583,434. Automatic exchange apparatus. AUTOMATIC ELECTRIC LABORATORIES, Inc. Oct. 27, 1944, No. 20918. Convention date, Jan. 22. [Class 40 (iv)] [Also in Group XIX] A traffic recorder for recording at regular intervals the busy or idle condition of the individual trunks in one or more groups, comprises scanning switches for testing the condition of the trunks, switches for counting the number of trunks found busy in each group during each testing cycle, switches for aggregating the numbers registered on the counting switches over a series of cycles, and date and time switches, together with electricallyactuated printing mechanism for recording the information supplied by the switches. Figs. 16-19 show examples of the record obtained for 5 groups of 10 trunks, 3 groups of 16, 2 groups of 25 and a single group of 50 trunks. In each case, the first line or heading shows a series of digits identifying the trunks, the number in each group and the date. Each succeeding line which represents one testing cycle shows a mark for each trunk found busy, the number of busy trunks in each group and the time at which the cycle occurs, while the last line shows the total number of busy trunks in each group over a prescribed number of cycles. The apparatus is assembled as a movable unit, Fig. 20, and is equipped with terminals for connection with the trunks to be observed and with key-switches for determining the grouping and for setting the date and time switches, the latter being provided with indicating lamps and being placed under the control of a time pulse unit when the start key is actuated. Three scanning switches are employed alternatively according to the grouping selected, and one of them serves both for the first and last groupings mentioned above by the use of a change-over relay. Two counting switches are used alternately and five sets of aggregating switches are provided, one of them being of larger capacity than the others for use with a single group of 50 trunks. At the beginning of each testing cycle, the trunks under observation are connected to a set of storage relays which energize or not depending on the condition of the individual trunks, busy trunks being grounded, and mark the terminals of the scanning switch accordingly. The heading of the record is printed during a preliminary cycle of the scanning switch, after which the conditions for testing are established by the advance of a sequence switch. The latter then steps on after every fourth testing cycle and after 60 cycles have been made at 15 second intervals initiates a final cycle to print the totals.

Abstract: 589,822. Fluid-pressure servomotorcontrol systems. BENDIX AVIATION CORPORATION. Oct. 27, 1944, No. 21015. Convention date, Nov. 9, 1943. [Class 135] [Also in Group XIX] Apparatus for indicating the ratio of one value to another comprises two slidable members carrying members bearing on opposite sides of a pivoted link, the distance of the first from the pivot being proportional to the first value and the force exerted by the second being proportional to the second value, whilst its distance from the pivot is adjusted by a servomotor to maintain the link in equilibrium and serves to measure the required ratio. One value is manually set through knobs 52, 53 in conjunction with a pointer and scale 44, 42 or through a remote control knob 48 through rack and pinion 45, 46 in conjunction with a pointer and scale 50, 51, thereby adjusting the distance (A) of a spring-loaded bearing member 17 from a pivot 3 for a lever 2. A second value is proportional to a fluid pressure (P) fed to bellows 25 which bears on the lever 2 through a member 24 at a distance from the pivot 3 controlled by a servomotor, which distance is indicated by a pointer and scale 41, 40 and gives the required ratio. In equilibrium, the lever is balanced in the mean position shown. Upon a decrease in A or increase in P, the lever 2 is displaced clockwise and through a link 6 and lever 8 causes valves 32, 33 to move to the right allowing a pressure fluid from an inlet 30 to flow through a duct 34 to move a piston 37 to the right, displaced fluid escaping through a duct 35 and outlet 29. The piston 37 moves the bellows 25 to the right until the lever 2 resumes its mean position and closes the ducts 34, 35 when the required ratio A/P will be indicated. Upon an increase in the ratio A/P, the process is reversed. To indicate the fuel-air ratio for an internalcombustion engine, the scale 51 may be calibrated to indicate rate of flow of fuel, while the interior of the bellows 25 may be opened to the air pressure at the air inlet of a carburetter through a conduit 26.

Abstract: 904,525. Toy vehicles. METTOY CO. Ltd. June 16, 1960 [June 19, 1959], No. 21101/59. Class 132 (3). The wheel axles of a toy vehicle are spring mounted so that they can move upwardly relative to the body. As shown, a toy car has a body, comprising a shell 4 and a base-plate 5 secured together by pillars 6. Wheel axles 10 are located in apertures 9 in walls 8 upstanding from depressed well portions 7 of the base-plate 5. A length of spring wire 12, located between the upstanding walls 8 and secured to the baseplate 5 by rivets 13, serves to spring mount the axles 10; the arrangement being such that the minimum clearance between the base-plate and spring at its point of engagement with the axle is greater than the diameter of the axle so that the force with which the springs press against the axle is never more than equal to the load carried by the axles. In alternative embodiments, the springs may be secured by bridge members formed integrally with the base-plate or may be trapped between the two parts of the body. The locating means for the axle may be formed on the shell instead of on the base-plate or partly on each. The springs may be formed by two or more separate wires or only a single centrally disposed spring may be provided. Separate wires may be employed as springs for the two axles instead of using opposite ends of the same wire. The wheels may be fixed to the axles and mechanical driving means may be geared to one or more of the axles.

Abstract: 651,495. Radio refracting devices. HUGHES & SON, Ltd., H., WHITFIELD, H. R., and HARRISON, A. Aug. 20, 1948, No. 22055. [Class 40 (vii)] In an installation for the transmission and/or reception of radio waves in which there is an obstruction which would of itself obstruct the propagation of electromagnetic radiation in a straight line between two points, means are provided associated with the obstruction for modifying the velocity of propagation of the radiation over such a region near the obstruction that the path of the radiation is caused to bend around the obstruction, whereby relatively free propagation of the radiation can take place between the two points. The arrangement is of particular use in connection with ship-born radar where masts and posts obstruct the " view " of the radar. In such cases it is desirable to have information about distant objects hidden by the obstruction even with some loss of bearing accuracy. One refracting device may comprise a series of metal plates 12 and 13 fixed to the obstructing post 10 in such manner that the sets of plates are symmetrical with respect to the plane through the post and the radar scanner. The sets may comprise eight or more parallel plates and for 3 cm. waves the spacing may be 1 inch and the plate area 1 sq. ft. The plates are tapered in shape as shown so as to refract radiation round the obstruction. Instead of stacks of plates, prisms of solid dielectric material (Fig. 2, not shown) may be used. These may be in the form of wedges with their broader ends adjacent to the post. In some cases a set of plates or block of dielectric may be placed on one side only of the obstruction.
